ONSEMI Bridge Rectifier Diode, Single Phase, 1.5A, 1.1V, 4-Pin SDIP - 400V
ONSEMI single-phase glass passivated bridge rectifier diode. 1.5A, 50A surge rating, 1.1V max VF. Ideal for mains rectification.
The ONSEMI Bridge Rectifier Diode is a high-performance, glass-passivated component designed to meet the demanding requirements of modern power supplies. As part of the advanced DFxS family, this single-phase rectifier sets a new standard in performance by addressing the ever-pressing need to improve power supply efficiency, enhance surge ratings, increase reliability, and reduce overall circuit size.
A standout feature of this bridge rectifier is its impressive forward surge current rating of 50A. In high-efficiency designs that strive to reduce circuit resistance, inrush surge currents can inadvertently increase. Consequently, a high surge current rating is essential to maintain and improve long-term reliability under these demanding conditions.
Efficiency is further optimised by achieving a maximum forward voltage (VF) of just 1.1V at 1.5A at 25°C. This lower forward voltage directly supports cooler and more efficient operation, making it an excellent choice for thermal management and energy-conscious applications.
Additional technical specifications include a maximum RMS bridge input voltage, a power dissipation of 3.1W, and a total capacitance per leg of 25pF at 4V/1MHz. The component is UL certified, ensuring compliance with rigorous safety standards, and features a surface-mount SDIP package with 4 pins for straightforward PCB integration.
Applications
This bridge rectifier is primarily utilised for mains rectification, offering reliable and efficient AC-to-DC conversion in a compact form factor. It is perfectly suited for power supply units, adapters, and various industrial and consumer electronics where space and efficiency are critical.
